Question

g "A protein is made from a messenger RNA of the following sequence. What is the sequence of amino acids for this protein? (Remember, a start and a stop codon are needed for a protein to be made).

Answer 1

Answer:

The correct answer is (amino) met - lys – phe

Explanation:

3' G C C G A U G G A U G A A G U U U U A A A G U A A U A G C A A U G G A G G A C 5'

Write the mRNA in opposite or reverse order as 5' to 3' and then start with AUG  codon.

Write the mRNA in revers order as 5’ to 3’ and starts with AUG codon.

mRNA—5’AUG-AAA-UUU-UGA-AGUAGGUAGCCG -3’      

Peptide: (amino) Met-Lys-Phe-STOP
